Abstract
A mobile delivery cart for the distribution of removable trays. The mobile delivery cart that is the object of this inventions contains a vertically moveable inner frame section which allows the loading and unloading of removable trays with decreased bending down and rising up. This also decreases the time needed for the loading and unloading of trays. The device includes an outer frame and an inner frame. The outer frame contains a plurality of tray supports in the top portion. The inner frame contains a plurality of tray supports. The inner frame is vertically mobile within the outer frame. The inner frame is moved to the top of the cart for loading and is loaded first. Once loading of the inner frame is completed it is moved to the bottom of the cart. The tray supports within the outer frame are then available to allow the upper portion of the cart to be loaded. Unloading is the reverse of loading. Because the two sections of the mobile cart that is the object of this invention are independent there is increased flexibility available to simultaneously transport a variety of items including those of different temperatures.
